The answer is TRUE.

If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.

Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.

Answer: It is true that the given example is an endothermic reaction.

Explanation:

Endothermic reaction is defined as the reaction in which reactant species absorb heat from the surrounding or from a source.

For example, DF + Heat \rightarrow D + F is an endothermic reaction.

Energy of products is more than the energy of reactants in an endothermic reaction.

On the other hand, a reaction in which heat is released by reactant species is known as an exothermic reaction.

For example, AB \rightarrow A + B + Heat is an exothermic reaction.

Energy of products is less than the energy of reactants in an exothermic reaction.

Hence, we can conclude that the given equation, DF + Heat \rightarrow D + F, is an example of an endothermic reaction.

For a particular reaction, Δ=−111.4 kJ and Δ=−25.0 J/K.
vichka [17]

Answer:

\Delta G =-103.95kJ

Explanation:

Hello there!

In this case, since the thermodynamic definition of the Gibbs free energy for a change process is:

\Delta G =\Delta H-T\Delta S

It is possible to plug in the given H, T and S with consistent units, to obtain the correct G as shown below:

\Delta G =-111.4kJ-(298K)(-25.0\frac{J}{K}*\frac{1kJ}{1000J} )\\\\\Delta G =-103.95kJ

Why do adults have stem cells
Eva8 [605]

Adults have stem cells because they are needed to repair certain tissues in the body such as in the muscles, bone marrow, skin, teeth, heart, and liver, to name a few. Thus, they can develop into many different cell types and function to replace older and damaged tissues.
